Zyrtec and antihistimines

I wish I had found this site a year ago. My 9 year old son was prescribed Zyrtec for his nasal allergies. He took it each day for over 6 months. He began to have problems in school - withdrawing from class participation, moody behavior at home, depression, lethargy, anxiety, worry, feelings of despair, told me that he would be better off dead! I started to panic but never associated the Zyrtec with his mental state. Took him to a counselor who said that he seemed like a normal, well-adjusted little boy who was sensitive. Realized that the Zyrtec was not really fully controlling his nasal allergies so decided to stop taking it for a while. Not much change in the allergies but the emotional change was amazing! I had my little boy back in only a few days after stopping the Zyrtec. First thing I noticed was that he was no longer mopey and lethargic and wondered if the Zyrtec had been making him tired. Then when the rest of his emotional issues disappeared magically I began to suspect the Zyrtec but the ped. dismissed my fears. A few months later he began to have bad allergies again so again tried an anithistimine for him. Zombie-like state returned right away. For some reason he is hyper-sensitive to all anithistimines and we avoid them all with him. What I learned from this is that doctors are not open to admitting that these drugs they so casually prescribe have serious side-effects.

I have been on Zyrtec for three years (Every day) haven't noticed mood swings in myself? My mother also takes them every other day and is not particularly moody. Although she has trouble sleeping which she attributes to the menopause But if i don't take one within 24hrs I get very itchy and hive up..now that I'm breastfeeding I've just noticed my daughter is very irritable..and am beginning to think it's related to the zyrtec. I'm changing to claratyne in the morning to see if there's a change..very,very interesting and scary reading all the side-effects!!
